DONALD E. WILLARD, OF DANVILLE, ILLINOIS, ASSIGNOR TO ALLITH-PROUTY COM-PANY, OF DANVILLE, ILLINOIS, A CORPORATION OF ILLINOIS.

SWIVEL PEDESTAL-CARRIER.

Specification of Letters Patent.

Patented Apr. a, 1916.

Application filed January 28, 1916. Serial No. 74,928.

To all whom it may concern:

Be it known that I, DONALD E. WILIIARD, a citizen of the United States,and resldent of Danville, in the county of Vermilion and State ofIllinois, have invented certain new and useful Improvements in SwivelPedestal-Carriers, of which the following 1s a specification.

My invention relates to carriers for use in mono-rail systems, andparticularly to an improved swivel carrier.

In the use of mono-rail carriers in shops, factories and yards it is, ofcourse, necessary to provide curves or turns in the track, and an objectin the present construction is to provide a carrier adapted for heavyservice and so arranged as to adapt itself to curves in the track. tothe end that friction may be eliminated to a material extent. I amthereby enabled to employ a lighter construction for the same service,due to the elimination of strains which would otherwise occur at curves.

A further object is to provide, in a carrier of this description, meanspermitting the ready removal of the supporting wheels and their bearingsfor substitution or repalr.

The invention will be more readily understood by reference to theaccompanying drawings, where- Figure 1 is a side elevation of a swivelcarrier such as contemplated by me; Fig. 2 is a plan view thereof, andFig. 3 is a section through a track of the character adapted to supportthe carrier of my invention and showing the carrier in end elevation.

The device may be considered as a truck and is composed of the framehaving the depending portion 10 and the laterally projecting pedestals11, 12. The pedestals provide recesses open at the bottom, the sidewalls of the pedestal members being curved as at 13 in Fig. 2, theradius of curvature being equal to one-half of the distance betweenopposed faces. The depending member 10 is provided with a centralaperture 14 for the accommodation of the shank of the supporting devicewhile the pedestal members are provided with vertical apertures 15, 16,at the center line of the recesses .formed therein.

Mounted in the spaces between the opposed faces of the pedestal jaws arejournal boxes 17, 18, the side faces 19, 20 of which ing employed toprevent the accidental dis placement of the boxes with relation to thepedestals. The upper portions of the journal boxes are shaped tocorrespond to the shape of the top of the recesses in the pedestals, butare of such shape as to permit of the ready swiveling of the boxes inthe pedestals. Mounted within the boxes on suitable roller bearings 24are axles 25, 26 to which wheels 27 are secured at their overhung end.

It will be noted that the arrangement is such that the journal boxes andwheels may be readily removed by withdrawing the cotter pins; that thetruck so constructed will adjust itself to curves in the track, therebypermitting a much shorter turn with less strain and friction; also thatthe device may be constructed very economically and is not likely tobecome out of order.

I claim:

1. In a carrier, the combination of a frame providing depending jaws,the opposed faces of which are curved, journal boxes mounted betweensaid jaws, the vertical faces of the jaws being correspondingly curved,and axles and wheels carried by said journal boxes, substantially asdescribed.

2. In a carrier, the combinationof a frame providing two pairs ofdepending between each pair of jaws, the vertical faces Signed atDanville, Illinois this 25th day of which boxes are curved to correspondto of January, 1916.

the curvature of the jaws, and means for DONALD E. WILLARD. removablysecuring said journal boxes in Witnesses:

5 place between said jaws, substantially as V ROY B. OLDER,

described. CIJ. ANDERSON.
